That's the findings of a report released by the Comptroller's Offices of Research and Education Accountability on attempts to control access to legal products sold at pharmacies which are later used to make meth.

The report also says the short history of laws to control drugs such as pseudoephedrine make it difficult to assess how effective those laws are at this point.

We've also learned that while meth production continues in Tennessee, the number of meth lab incidents has fallen. Police attribute the decline to the prescription-only policy for getting some ingredients used in meth.
